The EP 1/ EP 2 E-Connect pole lets you place one or even several mid/ high units on the EF 45 base or EA 600 amp. The pole is freely adjustable up to a length of 1.60 meters (EP 2= 0,605 meters), so you can set the height as you see fit by engaging its twist-lock fastener. No speaker cords are necessary thanks to the integrated bus.
